Two lines that intersect at a right angle are perpendicular.
Unless they are the exact same lines, no. Parallel lines do not touch. If two lines have the same intercept value, they share a point, and therefore touch.
Knowing that they have the same y-intercept, and knowing nothing else, the only thing you can say about the two lines is that they have the same y-intercept. That fact doesn't tell you anything else about them.
Coincident lines are essentially two linear functions whose graphs are the same; therefore, the two lines will have the same slope and the same y-intercept. When graphed, the lines will be one on top of the other.
No because two lines with the same slope but with different y intercepts are parallel lines. Perpendicular lines meet each other at right angles.

No. In order to be parallel, two lines would have to have the same slope, and different intercepts.Why? Two lines with different slopes, but the same intercepts would result in two intersecting lines. Two lines with the same slope, and the same intercept would result in the same line. Two lines with the same slope, and different intercepts would be parallel.
yes two lines that are the same line are parallel because they continue forever and do not intercept.
No, they cannot - unless the two lines are effectively the same line.
no solution
In two dimensions, are the same line.
Two linear equations (or lines) with the same y-intercept and different slopes are intersecting lines. They intersect at the y-intercept. If the slopes are negative reciprocals (ex: one slope is 3 and one slope it -1/3) then they are perpendicular lines.

They are coinciding which means they have an infinite number of solutions.
